Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy bending technology, and in particular to an aluminum alloy bending auxiliary device. Background Technology

[0002] Aluminum alloy bending is an important process in aluminum alloy processing. Aluminum alloys have the advantages of being lightweight, high-strength, and corrosion-resistant. After bending, they can be formed into structural parts of various shapes and are widely used in the construction, automotive, and electronics industries. Before bending, the appropriate aluminum alloy type and specifications are selected according to the specific application requirements and bending process. Different types of aluminum alloys have different mechanical and processing properties. During bending, the bending angle of the bending machine is accurately adjusted according to the design requirements. The deformation of the aluminum alloy is carefully observed, and the angle is adjusted in time to ensure the accuracy of the bending angle. After bending, burrs are removed using grinding tools and chemical methods to improve the surface quality and safety of the workpiece. In addition to the bending machine, auxiliary devices are also needed to assist in the bending process.

[0003] The proper use of auxiliary devices for aluminum alloy bending can save clamping time, improve production efficiency, and reduce problems during the bending process, avoiding rework due to workpiece quality issues, thereby improving overall production efficiency. It also prevents indentations and material deformation on the aluminum alloy surface caused by excessive localized stress, helping to maintain the flatness and integrity of the workpiece surface. However, existing aluminum alloy bending auxiliary fixtures mostly consist of two clamping plates and a screw. The clamping plates are connected by the screw, and rotating the screw can clamp and release the aluminum alloy material. However, these fixtures cannot position the area to be bent, preventing deformation of non-processed areas, which leads to reduced production quality and increased production costs. Utility Model Content

A connecting rod three is fixedly connected to the front side of the connecting rod two. A connecting rod one is fixedly connected to the front side of the connecting rod three. Multiple moving blocks are fixedly connected near the edge of the front side of the connecting rod one. A retaining block is slidably connected to the inner wall of each moving block. A spring is fixedly connected to the rear side of each retaining block.

[0008] As a further description of the above technical solution:

[0009] Mounting plates are fixedly connected to both the left and right sides of the connecting plate, and multiple screws are threaded onto the inner wall of the mounting plates.

[0010] As a further description of the above technical solution:

[0011] A washer is provided on the outer wall of the second screw, and the inner wall of the washer is slidably connected to the outer wall of the second screw.

[0018] As a further description of the above technical solution:

[0019] A rotating disk is fixedly connected to the top end of the threaded rod, and an anti-slip sleeve is fixedly connected to the outer wall of the rotating disk.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by placing an aluminum alloy plate on top of a C-shaped plate, and then rotating a threaded rod to allow the clamping plate to limit one side of the aluminum alloy, the limiting plate is pulled to drive the trapezoidal block to slide along the guide of the positioning plate, so that the T-shaped block can push the sliding plate downward through the T-slot.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of an aluminum alloy bending auxiliary device, comprising a C-shaped plate 1, with guide grooves 3 on both the left and right sides of the C-shaped plate 1. The C-shaped plate 1 is used to place the aluminum alloy plate to be bent. A lead screw 4 is threadedly connected to the inner wall of the guide groove 3, and a support rod 8 is provided on the outer wall of the lead screw 4. The lead screw 4 is used to rotate and drive the support rod 8 to move. A sliding plate 11 is slidably connected to the inner wall of the support rod 8. Positioning plates 5 are fixedly connected to the front and rear sides of the support rod 8. The guide groove 3 is used to provide guidance for the sliding of the support rod 8. A T-shaped groove 10 is provided on the top of the sliding plate 11, and a positioning plate 5 is slidably connected to the inner wall of the T-shaped groove 10. T-shaped block 13 and T-shaped groove 10 are used to guide T-shaped block 13 to slide within it. A trapezoidal block 12 is fixedly connected to the top of T-shaped block 13. A limit plate 7 is fixedly connected to the top of trapezoidal block 12. Trapezoidal block 12 can fit against the top of sliding plate 11, thereby pushing it to move. Positioning holes 6 are opened on the inner walls of trapezoidal block 12 and positioning plate 5. A pin 9 is slidably connected to the inner wall of positioning hole 6. An installation mechanism 2 is provided at the bottom of C-shaped plate 1. The installation mechanism 2 is used to quickly install the device. The pin 9 is used to be inserted into the positioning hole 6 to position the displacement between trapezoidal block 12 and positioning plate 5.

[0034] Specifically, after the trapezoidal block 12 and the positioning plate 5 are moved to the appropriate position, the operator can insert the pin 9 into the positioning hole 6 to fix the trapezoidal block 12 and the positioning plate 5 in the current position, preventing them from moving during the bending process, thereby ensuring the stability of the entire device and the accuracy of bending. When the operator rotates the lead screw 4, it will drive the support rod 8 connected to the outer wall of the lead screw 4 to move along the guide groove 3, thereby adapting to aluminum alloy plates of different sizes and bending requirements. The T-slot 10 can engage with the T-block 13, so that when the trapezoidal block 12 is pulled to move, the sliding plate 11 can be squeezed downward and lifted upward simultaneously.

[0035] Please see the appendix Figure 3 - Appendix Figure 5 The mounting mechanism 2 includes a connecting plate 201, which is located at the bottom of the C-shaped plate 1. The connecting plate 201 is used to support and connect the entire structure. Multiple mounting slots 202 are formed on the top of the connecting plate 201. A sliding rod 206 is slidably connected to the inner wall of each mounting slot 202. A locking groove 203 is formed near the edge of the inner wall of the mounting slot 202. The mounting slot 202 is used to guide the C-shaped plate 1 into the slot. A limiting plate 207 is fixedly connected to the front end of the sliding rod 206, and a connecting rod 207 is fixedly connected to the rear end of the sliding rod 206. 5. Link 205 is fixedly connected to the front side of Link 3 208. Limiting plate 207 is used to limit the sliding position of sliding rod 206. Link 3 208 is fixedly connected to the front side of Link 1 204. Link 1 204 is fixedly connected to the front side of Link 1 204 near the edge. Link 1 204 is used to transmit the movement of Link 3 208. The inner wall of the moving block 209 is slidably connected to the locking block 211. The rear side of the locking block 211 is fixedly connected to the spring 210, which is used to push the locking block 211 to slide and reset.

[0036] Specifically, the diameter of the limiting plate 207 is larger than the diameter of the sliding rod 206. When the sliding rod 206 slides in the mounting groove 202, the limiting plate 207 can prevent the sliding rod 206 from sliding out of the front end of the mounting groove 202, ensuring that the sliding rod 206 always moves within the specified range, thus ensuring the stability and safety of the device. The elastic force of the spring 210 can ensure that the locking block 211 is stably locked into the locking groove 203, thus ensuring the stability and reliability of the mounting mechanism 2. The shape and size of the locking groove 203 match the locking block 211, providing space for the locking block 211 to be locked in.

[0037] Please see the appendix Figure 5 - Appendix Figure 7Mounting plates 17 are fixedly connected to both the left and right sides of the connecting plate 201. Multiple screws 20 are threadedly connected to the inner wall of the mounting plate 17. The screws 20 are used to fix the mounting plate 17 in the required position. A sliding groove 24 is opened on the top of the moving block 209. A pull handle 23 is slidably connected to the inner wall of the sliding groove 24. The sliding groove 24 is used to guide the pull handle 23 to slide in it. A rubber sleeve 22 is fixedly connected to the outer wall of the pull handle 23. A washer 21 is provided on the outer wall of the screw 20. The inner wall of the washer 21 is slidably connected to the outer wall of the screw 20. The pull handle 23 is used to pull the rest of the structure to reset.

[0038] Specifically, the operator can apply a pulling force to the pull handle 23 along the direction of the slide groove 24, causing the locking block 211 to overcome the elastic force of the spring 210 and exit from the slot 203, thereby unlocking the entire installation mechanism 2. The washer 21 can increase the contact area between the screw 20 and the mounting surface, thereby dispersing the pressure of the screw 20 on the mounting surface and avoiding dents and damage to the mounting surface due to excessive local pressure. The washer 21 can also play an anti-loosening role, reducing the possibility of the screw 20 loosening due to vibration during equipment operation, and further improving the stability of the installation.

[0039] Please see the appendix Figure 2 - Appendix Figure 4 A nameplate 19 is fixedly connected to the left side of the connecting rod 205. A screw 18 is threadedly connected to the inner wall of the nameplate 19. The nameplate 19 can help users understand the relevant information of the device. A rotating disk 16 is fixedly connected to the top of the threaded rod 14. An anti-slip sleeve 25 is fixedly connected to the outer wall of the rotating disk 16. The screw 18 is used to fix the nameplate 19 in the required position. Multiple threaded rods 14 are rotatably connected to the top of the C-shaped plate 1 near the edge. A clamping plate 15 is provided on the outer wall of the threaded rod 14. The anti-slip sleeve 25 is used to increase the friction of the outer wall of the rotating disk 16.

[0040] Specifically, the anti-slip sleeve 25 increases the friction between the hand and the rotating disk 16, allowing the operator to rotate the rotating disk 16 stably even when their hands are oily or wet. The nameplate 19 helps the user identify the specifications and applicable scope of the device. The screw 18 can fix the nameplate 19 in the required position, so that the nameplate 19 can be quickly observed. When the threaded rod 14 is rotated, the clamping plate 15 will move up and down along the axis of the threaded rod 14 under the action of the thread. The position of the clamping plate 15 can be adjusted according to the thickness and shape of the aluminum alloy workpiece to achieve precise clamping of the workpiece.

[0041] Working principle: When it is necessary to bend the aluminum alloy, first place it on top of the C-shaped plate 1, then rotate the threaded rod 14 so that the clamping plate 15 can press one side of the aluminum alloy. Then rotate the screw 4 to adjust the position of the support rod 8 on the inner wall of the guide groove 3 so that it can be aligned with the position to be bent. Then slide the limiting plate 7 between the adjacent positioning plates 5 to drive the trapezoidal block 12 to slide. It can be driven by the engagement of the T-shaped block 13 and the T-shaped groove 10, thereby pushing the sliding plate 11 to slide up and down on the inner wall of the trapezoidal block 12 so that its bottom is in contact with the top of the aluminum alloy plate. After reaching the appropriate position, insert the pin 9 into the positioning hole 6 for limiting. Then start the bending machine to bend the back side of the aluminum alloy plate, while the front side is limited by the sliding plate 11 and the clamping plate 15.

[0042] When the device needs to be installed in the required position, first fix the connecting plate 201 in the required position with screw 20, then insert the C-shaped plate 1 into the mounting groove 202. As the C-shaped plate 1 slides in the mounting groove 202, it will press the limiting plate 207, thereby pushing the sliding rod 206 to push the connecting rod 205, which will drive the connecting rod 208 to slide backward, thereby pulling the connecting rod 204 to drive multiple moving blocks 209 to slide into the mounting groove 202 until the outer wall of the limiting plate 207 is in contact with the rear side of the inner wall of the mounting groove 202. At the same time, the outer wall of the locking block 211 will also be in contact with the inner wall of the slot 203. Then, the spring 210 will push the locking block 211 into the slot 203, thereby limiting the position of the moving block 209, and thus limiting the position of the C-shaped plate 1, completing the installation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
